Flat supersonic jet mill

Operating principle

The pressure gas by feeding the ejector nozzle to produce high-speed jet and form negative pressure in the feed mixing chamber, so that the crushed raw materials automatically inhaled into the mixing chamberand the jet is injected into the grinding chamber, several nozzles of the periphery of the grinding chamber jet supersonic jet forward to the grinding chamber, so that the particles into the crushing chamber are violent collision and milling then crushed. Coarse particles loop back to the smash indoor to continue crushing, the fine particles in the center of the discharge port discharge, at last gained uniform ultrafine particles.

Performance characteristics

1.It is used in dry supermicro technology, as the high impact velocity, can be up to Mach 2.5 above, under normal circumstances, easy access to the 1-10 micron particles.
2.As the self-classification of grinder inner, coarse particles in the products endless cycle of crushing, which can get uniform particle size distribution of a small range of products.
3.At the crushing process, due to the compressed air expansion, the temperature decreased, it is applied to the crushing of the low melting point, heat-sensitive materials, also play a role in the effect of mixing and dispersion at the crushing process.
4.The device has a short crushing time, simple structure, there is no running of moving parts and easy maintenance, operation, small footprint, low noise and vibration advantages.
5.The high grinding efficiency, continuous grinding, to maintain the crushed products purity.

Scope of application

The machine is widely used in pharmaceutical, traditional Chinese medicine, pesticide, chemical, metallurgy and other industries of ultra-fine grinding materials, such as carbendazim, methyl tozin, herbicides, silica, pigments, dyes, nimodipine, cortisone and so on.
